Rokitamycin (RKM), a 3"-O-propionyl derivative of leucomycin A5, is bactericidal against staphylococci near the minimum inhibitory concentrations. RKM bound to ribosomes before-hand is only slightly displaced by erythromycin or josamycin, or even by RKM itself. The adhesive binding of the RKM-ribosome complex might prove to be the lethal event for susceptible staphylococci.
罗他霉素(RKM)是柱晶白霉素A5的3″-O-丙酰基衍生物,在接近最低抑菌浓度时对葡萄球菌具有杀菌作用。预先与核糖体结合的RKM仅被红霉素或交沙霉素轻微取代,甚至被RKM自身轻微取代。RKM-核糖体复合物的黏附性结合可能是敏感葡萄球菌的致死事件。
